Not Applicable
Conditions
Autism Spectrum Disorder
Interventions
Behavioral: Pictures
Behavioral: Startle eliciting noise
Registration Number
NCT01322984
Lead Sponsor
University of Tromso
Brief Summary

Children and youth diagnosed with autism spectrum disorder (ASD) have been shown to react abnormally to social stimuli, especially to human faces. Children and youth with ASD show less interest in social stimuli, and may even avoid looking at or interact with such stimuli. It has been proposed that social stimuli elicit reactions like fear and stress in individuals with ASD, and this explains the lack of interest and avoidance. The present project investigates this hypothesis.

Primary Outcome Measures
NameTimeMethod
The eyeblink of the Startle reflex is measured.The startle reflex will be measured in relation to picture presentations during the experiment (e.g. day 1).

The startle reflex is potentiated when participants are influenced by negative emotions. Accordingly, startle will be measured in relation to picture presentation to gauge the emotional effect of the pictures. It is expected that the ASD group will show fear potentiated startle to pictures of human faces.
